To all whom it may (6'32 sewn Be it known that L Wm/rm citizen of the United lfiizzies residing in izbe city of Pbilzu'lslphizi, county of ihiladelpllia, and Siam of lsnn bxziniii have, in-

vented cert-sin improvements in Electric Switches, of which the following is a specification.

This invention is an electric switch chain sctei'ized, in its )1': ,i'er1:ed vonsti'uciion, by

the combination with it case of oscillatory plural pole make and break mechanism provided with fusss that can be replaced in the open position of? the: swim-b witlioufl if, opening the case ans with means for effect" ing automatically vibe quick throw of the switch in making and breaking the sire it.

The improvements provide the ilesidemts of gm externally operated quid: throw switch 20 hri ving fuses can be replaced While the contacis are infiilis open relation and fully enclosed cont-acts that dssd the switch is in the open posifiion, safety in both abs open closed PSSii'IlOIHS, and imma- 25 tei'iaiity as in how the Elm and load connections are made.

The improvemen'is as embodied in mechanism set out in fine iciiowing descriplion imcl tbs accompanying drawings in 39 iliiist ization thereof.
